we are trying to add an additional ID Number (e.g. Driving License ID) to the patient registration form.
We managed to create a Driving License ID in “Patient Attribute Types” and we can search for that ID Number by using the standard OpenMRS Find/Create Patient function within the “advanced configuration” screen.
Unfortunately we cannot get this Diving License ID on the “register patient” form.
If you can’t find a solution to add an identifier to the registration app, you could always create it as a person attribute and add that per the directions on the page referenced above.
